Win32 event notifiers are not file descriptors, so they will not be able
to use qemu_set_fd_handler. But even if for now we only have a POSIX
version of EventNotifier, we can add a specific function that wraps
the call.
The wrapper passes the EventNotifier as the opaque value so that it will
be used with container_of.
